I disagree to a certain point with the other two reviews. Neither is it a stupid, boring film, nor is it a comedy! It is not a comedy unless we consider it a "human comedy", like a tragedy can be comedy too. So do not expect to laugh a lot and hear many witty lines or see many jokes. It is a psychological story with a few comedic touches. However, it does not mean it is a poor film. Far from it, I think it has a profound sense, it asks what it means to be happy in a relationship, including a marriage, and why should a marriage linger on if the people in it do not have feelings for each other anymore. It is tricky and nuanced because none of the four characters is showed as a black, unlikeable character, even the two doing the initial cheating. They are simple normal, flawed people but not without positives. And the two lovers do have real feelings for each other, which the whole point of the story, because if it was pure sex the story would not make sense. But what happens if u meet and fall in love with a person other than your spouse? U carry on regardless, for the sake of conveniences and maybe for your children, or u try to lead a double life? I thought for many minutes of the film that lack of real anger, pain and passion that the two cheated spouse do NOT show is a true weakness of the script and directing. But then the cheated man asks the cheated woman if she really loves her husband and the answer was ambiguous. Of course, she said, he is my first man, a husband of my child etc. Sounds more like an old sweater. The story revealed that below the schematic, superficially happy family life even the cheated pair had not real passion left anymore, although maybe they did not realize that.
